J. R. VAN WORMER KNOCKDOWN BOX Filed April 10.` 1928 Patented Dec. 8,1931 JOHN R. VAN WORME, OF .TOLEDFQ OHIO KNooKnowN nox Application ledApril 10,

This invention relates to knock down containers of the collapsible boxtype.

This invention has utility in ready rigid set-up boxes for convenientcharging of material thereinto.

Referring to the drawings: y

Fig. 1 is a perspective view of a closed box hereunder, in set upposition;

Fig. 2 is a blank of the box of Fig. 1;

Fig. 3 is the blank of Fig. 2 as assembled into a knock down box;

Fig. 4 shows the knock down or collapsed box of Fig. 3 with its bottomflattened and its ends set up;

Fig. 5 is the box of Fig. 4 with the end stiening means elevated againstthe ends therein;

Fig. 6 is a perspective View of the box of Fig. 4 with the tuck-inadditionally anchor'- ing the end set up stiifening means; and

Fig. 7 is a section on the line VII-VII, Fig. 6.

rPhe box hereunder is conveniently made from a single strip of cardboard comprising top 1, side 2, bottom 3, 4, Jfront side 5, and tuck-in6. Hinge connections 7 assemble these top, sides, and bottom sections,as well as the tuck in section, in a continuous series. The top 1 isshown as having end extensions 8. The side 2 is provided with box endproviding sections 9 terminating in hinge providing portions 10 havingminor extensions 11, The bottom sections 3, 4, are provided with end setup stii'ening means 12, 13. The front side 5 is shown as provided withend sections 14. rl`hese end sections 14 may have the minor extensions11 sealed therewith lon the inner side, thus to leave a flush exterioror end portion of the end sections 9, 14. These extensions or endportions 8, 9, 12, 18, 14, have hinge connections 15 with theintermediate portions of the box blank unit.

The end set up stiiening means are shown as provided with lugs orwidening minor extension portions 16 adjacent the hinge mounting 15,with the bottom portions or sections 3, 4. The bottom sections 3, 4,have medial hinge connection 7 andA the extensions 12, 13, have medialhinge connection 17 therebetween. 1

Y1With the box blank assembled into a knock Vdown box by adhesiveconnecting the minor extensions-1.1 of the end portions 9 to the endportions 14,'the box may be conveniently shipped in flat compact form.vln order to bring the box into position for use, the operator merelypulls the side 5 away from the side 2, thus swinging the ends 9, 14,into alignment from the respective sides 2, 5. This operation spreadsout the bottoni 3, 4, into a common planev so that the end set-upstiffening means 12, 13, as flat on the bottom (Fig. 4) may then b-eswung upward against the ends 9, 14 (Fig. 5). There is .trictionalholding of these ends set-up stiening means due to the widening regions16 frictionally coacting with the respective sides 2, 5, adj acent thecorners 15.

In addition to this stability providing frictional holding of the endset up means, a more positive holding is here more readily effective dueto the tuck-in 6 from the side 5, which as folded inwardly against theinward side of the side 5, engages the end set up stiifening means 13and thus holds such against the end sections 14 and accordingly againstcollapse toward the bottom of the box. The operator accordingly may atthis pulling out of the box and setting up of the stii'ening means, thencollapse the tuck-in 6 to hold it in tucked in position, thus retainingthe box in its full set-np assembly in order that the charging ofmaterial thereinto as donghnuts, cookies-or other material may quicklyoccur. As this operation is completed, the top 1 may be swung toward theside 5 with theextensions 8 thrust between the end set up stiffeningmeans 18, 12, and the ends 9, 14, or even allowed to fold down on theoutside, there to be engaged by sealing strip 18 in effecting inalclosing in set up position of the knock down box into a rigid chargedcontainer. n

What is claimed and it is desired to secure by Letters Patent is:

A knock-down box unit of integral blank formhaving in a series top,back, medially foldable bottom, front and front tuck-in,

outer foldable ends hinge connected between the front and back, saidbottom having a up stifening means to hold the inner and outer scoringfor the medial folding thereof and having supplemental inner end set-upstiffening extensions hinged to the bottom to intersect said bottomscoring at said ends and said scoring being continuous past saidintersecting to render said ends lmedially foldable, said stiffeningextensions as set up forming with the front and back connecting endstwoply upwardly extending ends for the box, said tuck-in beingindependent of the kextensions and hinged along the upper edge of thefront opposite to the top mounting and foldf able into the set-up boxagainst the end setends together at the top and thereby lock the box setup against medial folding in of the box bottom, the box top beingswingable thereover into box closing position.

In witness whereof I aiix my signature. Y v
